Well, it seems the back and forth of N54 tuning horsepower records is over... for now. Earlier this month Vargas Turbo Tech and Pro Tuning Freaks (with a Cobb flash) set the N54 hosrepower record at 693 wheel horsepower. That basically obliterated what anyone else had hit on this platform. A competing tuner with a single turbo (the Vargas VTX63 upgrade consists of twin turbos) N54 upgrade kit out of nowhere pulled out suspect numbers that eeked out a few more wheel horsepower.

This became an ego pissing match of sorts but Vargas and Pro Tuning Freaks went back to the dyno to make some adjustments and managed to surprisingly quickly and easily take the horsepower record right back (and where it rightfully belongs due to the breakthrough being thanks to the Vargas work with the High Pressure Fuel Pump) with a 725 wheel horsepower pull.

A video is included below along with two graphs. The E92 335i is equipped with a Pro Tuning Freaks pro tuning using the Cobb flash system, 109 octane race gas, meth injection, and of course the Vargas Turbo Technologies VTX-R 63 (GTX2863R) twin turbo upgrade and HPFP upgrade.

Congratulations to Vargas, PTF, and Cobb for pushing the platform into new territory.

so how much meth are we talking here? what meth system and at what throttle %/rpm is it triggered?
also 0 smoothing means nothing when the graphs stretched so hard. can we get one scaled less rectangular with AFRs?

edit: $#@! the HP...that is awesome torque for a late model bmw motor!

HFS-4 comes in at around 15 PSI, keep in mind we made 673 with no meth at all. On the 109 we prob didnt even need it, but used it to keep IAT's down on the dyno. Keep things that much safer.

I really wish we knew for sure this will fit in a 135i without issue. If it needs some slight modifications to the engine bay that's fine. There's a couple nice 135's with 6MT and Nav but I would hate to buy it only to find out 3 months from now stage 3's wont fit...

This is key. I've always wanted a girl that can support herself, and does not need to rely on me. I think an electrical engineer and a pharmacist make a good combo, although she does make more than me. I'm alright with that though. It's not like I bag groceries. She's also four inches taller than me, but at 5' 6" I got over that a long time ago. Really narrows down the selection if I only look for girls shorter than me with around six figure incomes. Neither of us are particularly compelled to have children either - praise science for hormonal contraception.

Mine is an electrical engineer and I'm a computer engineer We don't want kids and don't care about the marriage thing either.
